WHEELED SCRAPER.

SPECIFICATION forming part of Letters Patent No. 557,330, dated March 31, 1896. Application filed May 23,1893. Rene red September 23,1895. Serial No. 563,391. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. J OHNSON, of Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Wheeled Scrapers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to. an improvement in wheeled scrapers, the object of the invention being to construct a wheeled scraper in such manner that when the bowl or scoop is raised the forward end thereof will move faster and to a further extent than the rear end and thus prevent the escape of the contents of the bowl or scoop.

A further object is to produce a wheeled road -scraper which shall be simple in con struction, easy to operate and effectual in the performance of its functions.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts,as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view illustrating my improvements. Fig. 2 is a plan view. Fig. 3 is an end view.

A represents a bent axle carrying wheels B B at its ends. On the raised portion of the axle A, at or near the ends thereof, the forward end of the frame of the machine is mounted, said frame comprising bars 0 C, which are bent at their rear ends to approach each other and support between them, in proximity to their rear extremities, a box D for the reception of the shank a of a bracket 19, which carries a caster-wheel E. A bar or bolt 0 passes through the rear extremities of the bars 0 and projects somewhat beyond its bearing in said bars. To this bar or bolt 0 the rear ends of arms F are pivotally connected, the forward ends of said arms being secured to a scoop or bowl G, said scoop or bowl being located directly under the axle A. I prefer to provide the scoop or bowl Gwith a tilting bottom cl and a lever e, by means of which to operate it.

A shaft H is mounted on the bars 0, and between its ends pulleys or drums f are secured and adapted for the reception of chains or ropes f, the lower ends of which are secured to the scoop or bowl G, preferably at points about midway between its ends, thus supporting the forward end of the scoop or bowl.

To one of the wheels B of the machine a gear-wheel I is secured and adapted to mesh with a gear-wheel I loosely mounted on the shaft H. A clutch-sleeve 9 projects from the hub of the gear-wheel I, and is adapted to be engaged by a clutch-sleeve g adapted to have a sliding movement on the shaftH and rotate therewith. The clutch-sleeve g is made with a groove 9 for the reception of the bifurcated end of a pivoted lever I whereby to throw it into and out of clutch with the clutch-sleeve When the machine is in operative position, the parts will be in the positions shown in Fig. 1. After the scoop shall have been filled and it be desired to convey it to a place of deposit the lever I will be operated to throw the clutch-sleeves g g into mesh, whereupon motion will be imparted to the shaft H and the chains or ropes f wound on the pulleys or drums f, thus raising the scoop. The rear end of the rigid arms F of the scoop being pivotally supported at the rear end of the machine, it will be seen that when the scoop is raised it will move in the arc of a circle, the free end of the scoop moving faster and farther than the rear end, and made to assume the position shown in dotted lines in Fig. 1. When the scoop shall have been sufficiently raised, the clutch-sleeves will be thrown out of gear, and the shaft H will be prevented from rotating to lower the scoop by the engagement of a lever 71. with a ratchet-wheel 2' carried by said shaft.

My improvements are very simple in construction, cheap to manufacture and effectual in the performance of their functions.

Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details of construction herein set forth; but, 7

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a wheeled scraper, the combination with a frame extending rearward from the main wheels, of a scoop suspended from the scraper and provided with rearwardlyextending arms rigid therewith, the rear ends of the arms hinged to the rear ends of the scraper-frame, and a caster-wheel the shank of which is connected with the rear end of the frame, substantially as set forth.

2. In'a wheeled scraper, the combination with a frame extending rearward from the main wheels, of a scoop having arms rigid therewith and extending rearward, said arms hinged to the rear end of the frame, means for suspending the scoop and raising and lowering it, and a caster-wheel the shank of which is connected with the rear end of the frame, substantially as set forth.

3. In a wheeled scraper, the combination with a frame extending rearward from the main wheels, of a scoop suspended from the scraper and provided with rearwardly-extending arms rigid therewith, the rear ends of the arms hinged to the rear ends of the scraper-frame, and a caster-wheel the shank of which is connected with rear end of the frame at a point forward of the point of connection therewith of the arms on the scoop, substantially as set forth.

4. The combination with an axle, frame, and caster-wheel supporting the rear end of the frame, of a scoop having arms extending rearward and pivoted at their rear ends to the rear end of the frame, a pivoted bottom to the scoop, and a handle connected with the pivoted bottom for tipping the contents of the scoop rearward when the scoop is elevated, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

BENJAMIN F. JOHNSON.
